The Challenge

Power for decommissioning of a major offshore platform

The field was discovered in the 1980’s, with production beginning roughly 10 years later. In the mid 2000’s, the field reached the end of its economic life. When the platform was producing power it was supplied by gas turbines that were included in the first phase of decommissioning.

The customer needed a solution to provide transitional power to allow the shutdown and decommissioning of the platform turbines, and to International Oil and Gas Major North Sea Oil and Gas provide ongoing continuous power to allow the remaining decommissioning programme to continue.

Power generation is one of the most important considerations when operating an offshore platform and its reliability is closely linked to the safety of the personnel on the platform. The client needed a reliable provider with dependable equipment to come up with a solution.

All equipment was subject to a rigorous 5-day factory acceptance test at Aggreko’s Dumbarton facility prior to shipping offshore. The duration of the project was originally expected to be around 3-4 years from a shipping date of August 2009. They were finally removed eight years later in August 2017.

During this time, permanent platform personnel completed daily/weekly upkeep on the equipment, and Aggreko technicians undertook more complex technical maintenance during planned quarterly visits.

As a proactive measure, due to the extension of the hire period, Aggreko swapped the generators out in 2014, to maintain the consistent levels of reliability that the package delivered.
